Comparison of three common software-defined network controllers

<p>The software-defined network (SDN) controller adds and removes the contents of flow table through secure channels to determine how packets are processed is managed. The pays attention intelligence becomes middle part, where manages transfer data aircraft delivered via OpenFlow (OF) switch. To this end, provides an interface for managing, controlling, managing switch table. Run tests calculate throughput latency levels test using cbance tool, which can transmission control protocol (TCP) user datagram (UDP) protocols. run by forcing at maximum without any additional settings (default settings) in order use correct information about controller’s capabilities. Because need, you need performance your controller. In study, were on three popular controllers. Test results show that flowed controllers more stable than open operating dystem (ONOS) daylight (ODL) host loads.</p>
